Submit Form Not Updating Back-end SharePoint List When Removing Data from a Field

[Ms-PowerRanger2]

I have a SharePoint List record that I'm updating via PowerApps. 

1. If I update a field (like a date field) (by replacing the date with a new date), then submit the form, It updates the back-end SharePoint List
2. If I update a field (like a date field) (by removing the current date and leaving blank), then submit the form, It does not update the SharePoint List

This seems to be an issue on our clients environment but not in our environment.

Any ideas on what to do or look for?

I think if the field is required, SP wont accept a blank update..

In your App Settings, turn on the Formula level Error Management.  It's the only way you can write a blank value to the datasource currently.

I hope this is helpful for you.

Thanks Randy!  That took care of it!  That's interesting that this setting is under the Experimental section.  I had it turned on in our environment and wondering if the setting may have not come through with the export and import of the Application.  (If this setting is suppose to stick with an export/import of an application, then I could have set it in our environment after exporting)

Thanks for the quick response!

Thanks for your fast reply.  The field isn't required but Randy Hayes suggestion of turning on the Experimental setting "Formula level Error Management" worked.

No problem.  Yes, it's quite possible the setting did not translate over to the other environment.  I'd always check through from one to the other whenever you import just to be sure.
